In .NET applications, we can set the Form.Cursor property to a Cursor object to change the Form’s cursor. The Cursor object can be created from four sources: a specified Windows Handle, a specified Data Stream, a specified File Name, or a specified ResourceType and CursorName. The following four constructor functions of Cursor are mapped to the above four object creation sources:
1. IntPtr

2. Stream

3. String

4. Typ, String

Some system cursors cannot be loaded directly using the full path file name because they are in a native format which managed code is not aware of. In that case, we should call the Windows API LoadCursorFromFile using PInvoke, and then choose the first pattern to create a Cursor object from a File Handler. C# codes look like,
------------------------------------------------------------
[DllImport("user32.dll", SetLastError = true, CharSet = CharSet.Auto)]
private static extern IntPtr LoadCursorFromFile(string path);
private void Form1_Load(object sender, EventArgs e) {
this.Cursor = new Cursor(LoadCursorFromFile(@"c:\windows\cursors\hand.cur"));
}
------------------------------------------------------------
